MetaMask

MetaMask: self-custody wallet for EVM chains, Solana, and Bitcoin

MetaMask is one of the most widely used self-custody crypto wallets. It started in 2016 as an Ethereum browser extension and is now available as an extension and as mobile apps. It holds Ethereum and EVM-chain assets, Solana, and Bitcoin, connects to decentralized apps, and includes built-in swaps and other financial features. You hold the keys: MetaMask cannot access or recover your funds.

What it is

MetaMask was built by Consensys. In September 2026, Consensys Software Inc. announced it will split into two companies: the existing company becomes MetaMask, focused on the consumer wallet, and a new Consensys takes Linea, the Besu and Teku clients, and the institutional business. The split is expected to finish by the end of 2026. The wallet itself continues as before.

MetaMask now uses multichain accounts, where one account manages EVM, Solana, and Bitcoin addresses together. Native Solana support arrived in 2025, and native Bitcoin support followed in December 2025 with native SegWit addresses.

Key features

• Multichain wallet: Ethereum and EVM networks such as Linea, Base, Arbitrum, Optimism, Polygon, and BNB Chain, plus Solana and Bitcoin. You can add other EVM networks manually.
• dApp connections: connect to DeFi, NFT, and gaming apps and sign transactions.
• Swaps and bridges: built-in swap and bridge aggregators, with a fee included in the quote.
• Security alerts: transaction simulation and alerts that warn about known malicious contracts and phishing sites.
• Hardware wallet support: pair Ledger, Trezor, and other devices so keys stay offline.
• Snaps: third-party plugins that add features and extra networks.
• mUSD: MetaMask's own dollar stablecoin, issued by Bridge (a Stripe company) on Ethereum and Linea.
• MetaMask Card and other services: a payment card for spending crypto, perpetual futures, and yield products. Availability varies by country, and several of these are offered through third parties.

Security

• Secret Recovery Phrase: your 12-word phrase controls every account in the wallet. Write it down offline and never share it. MetaMask staff will never ask for it.
• Hot wallet risk: keys live on an internet-connected device. For larger amounts, pair a hardware wallet.
• Signature phishing: malicious sites often ask for token approvals or off-chain signatures that let them drain funds. Read every request and revoke approvals you no longer need.
• Recent incident: on September 30, 2026, MetaMask disclosed a security incident affecting part of its infrastructure and began exiting its staking validators. It said there was no indication that wallets or customer funds were affected. Check MetaMask's official news page for updates.
• Rewards and tokens: MetaMask says it has no plans for a MASK token. Treat any "MetaMask token airdrop" as a scam.

MetaMask and Vaulta

MetaMask does not support native Vaulta (formerly EOS) accounts by default. Two options exist:

• Vaulta Wallet Snap: Unicove, the Greymass web wallet, publishes a guide to using a MetaMask Snap to sign Vaulta transactions.
• Vaulta EVM: the EVM layer formerly called EOS EVM uses chain ID 17777 with A as its native token. When this listing was checked, the documented public RPC and explorer addresses did not resolve, so confirm current endpoints in the official Vaulta documentation before adding the network.

For everyday Vaulta use, a native Antelope wallet such as Anchor is usually simpler.

How to get started

• Download MetaMask only from metamask.io or the official app stores.
• Create a new wallet, set a password, and write down your Secret Recovery Phrase offline.
• Choose your network, fund your account, and keep some native token for fees (for example ETH on Ethereum).
• Connect to dApps through their "Connect wallet" button and review each request.

Pros and cons

Cons

• Hot wallet, so it is a frequent phishing target.
• Swap and bridge fees are higher than going direct.
• Card and financial features depend on your country.
• No native Vaulta account support without a Snap.
